How does heat flow?

• Always from cold to warm
• Always from warm to cold
• Both warm to cold & cold to warm
• It depends on the temperature

What is heat energy?

• Heat is a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy.
• Energy from heat
• Heat that gives of multiple types of energy for multiple reasons.
• Nothing, it really doesn matter to much rather it´s just...Heat.
